Abstract

Systems and methods for providing service and to computing devices. In some embodiments, an Information Handling System (IHS) includes a Basic I/O System (BIOS) and a memory coupled to the BIOS, the memory including program instructions stored thereon that, upon execution by the IHS, cause the IHS to: determine that the IHS is operating in a degraded state; and initiate one or more support, diagnostics, or remediation operations in response to the determination.

Description

FIELD
• This disclosure relates generally to computer systems, and more specifically, to systems and methods for providing service and support to computing devices.
BACKGROUND
• As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an Information Handling System (IHS). An IHS generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, IHSs may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in IHSs allow for IHSs to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, global communications, etc. In addition, IHSs may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
• In many situations, an IHS may need to be serviced or supported. For example, the IHS may have hardware and/or software that needs to be fixed, updated, removed, installed, or replaced from time to time. To address these, and other problems, certain systems and methods described herein may enable a computer manufacturer or service provider to allow customers to have access to automated, simplified support actions or operations, for example, even when an IHS is not otherwise able to boot to its main Operating System (OS) or has other serious hardware or software failures.
SUMMARY

• In yet another illustrative, non-limiting embodiment, a memory device may have program instructions stored thereon that, upon execution by an IHS, cause the IHS to: determine, by a BIOS, whether the IHS has network access and, in response to the network access being unavailable, performing one or more local support, diagnostics, or remediation operations; in response to the network access being available, connecting to a backend service configured to perform one or more warranty or service entitlement checks using IHS identifying information; and uploading telemetry or debug data to the backend service, where the backend service is configured to perform one or more remote support, diagnostics, or remediation operations upon the IHS.
• The program instructions, upon execution by the IHS, may also cause the IHS to determine whether a main OS has booted and, if the main OS has not booted, determining whether a service OS has been booted, and: (i) in response to a determination that the service OS has not booted, performing the one or more local support, diagnostics, or remediation operations in pre-boot mode; and (ii) in response to a determination that the service OS has booted, performing the one or more local support, diagnostics, or remediation operations in pre-OS mode.
• In some embodiments, one or more of the techniques described herein may be performed, at least in part, by an IHS operated by a user. In other embodiments, these techniques may be performed by an IHS having a processor and a memory coupled to the processor, the memory including program instructions stored thereon that, upon execution by the processor, cause the IHS to execute one or more operations. In yet other embodiments, a non-transitory computer-readable medium or memory device may have program instructions stored thereon that, upon execution by an IHS, cause the IHS to execute one or more of the techniques described herein.

DETAILED DESCRIPTION
• To facilitate explanation of the various systems and methods discussed herein, the following description has been split into sections. It should be noted, however, that the various sections, headings, and subheadings used herein are for organizational purposes only, and are not meant to limit or otherwise modify the scope of the description or the claims.
• A. Overview
• The inventors hereof have recognized a need for providing systems and methods for service and support to computing devices. Existing tools intended to facilitate service and/or support of a client device or Information Handling System (IHS) do not adequately address numerous problems, such as, for example, situations when the IHS fails to boot a main Operating System (OS) for any reason, whether due to a hardware of software problem, such that the IHS is said to be in a “degraded state.” To address these and other concerns, embodiments described herein provide Basic I/O System (BIOS) and/or service OS-level intelligence to enable a client device to self-diagnose and to receive automated service and support. Additionally or alternatively, in some embodiments, the main OS may be modified to implement one of more of the foregoing features.
• The term “degraded state,” as used herein, refers to the state of an IHS that is not capable of booting a main OS (e.g., WINDOWS®, MAC OS®, LINUX®, etc.), either fully or partially (e.g., in WINDOWS®'s “safe mode” or the like). When operating in a degraded state, the IHS may still be able to execute BIOS instructions and/or a “service OS” (SOS).
• The term “BIOS,” as used herein, refers to a type of firmware used during an IHS's booting process (e.g., power-on, or reset). The BIOS initializes and tests an IHS' hardware components, and loads a boot loader or an OS from a memory device. The BIOS additionally provides an abstraction layer for the hardware which enables software executed by the IHS to interact with certain I/O devices such as keyboards, displays, etc. Incidentally, the Unified Extensible Firmware Interface (UEFI) was designed as a successor to BIOS to address certain technical issues. As a result, modern IHSs predominantly use UEFI firmware and the term “BIOS,” as used herein, is intended also encompass UEFI firmware and future variations thereof.
• The term “service OS,” as used herein, refers to one or more program instructions or scripts distinct from an IHS's “main OS” such that, upon execution by an IHS (e.g., upon failure by the IHS to load the main OS), enable one or more support, diagnostics, or remediation operations to be performed independently of the state of the main OS. The service OS may include one or more service and support applications, as described in more detail below. In some cases, an SOS may be stored in a recovery partition of a hard drive. Additionally or alternatively, an SOS may be stored in a Non-Volatile Memory (NVM) or flash memory built into the client system. Additionally or alternatively, the SOS may be stored in a remote location so as to allow an IHS to boot remotely “from the cloud.”
• In some embodiments, service capabilities may be invoked either “pre-boot” or “pre-OS.” Pre-boot capabilities may be built into the BIOS/UEFI, and pre-OS capabilities may be provided by a service OS. For example, pre-boot services may include using enhanced BIOS diagnostics tools to detect hardware failure, providing a Quick Response (QR) code to simplify access to support services, etc. Meanwhile, pre-OS services may include enabling a service OS to provide customer automated assistance, using built-in remediation scripts to help diagnose and remediate the device, improve support efficiency using live chat, remote control support, etc. In some implementations, pre-boot services may be focused on “no-boot” scenarios, whereas pre-OS services may be focused on operations such as remediation, boot from web, re-imaging from web, etc.
• As will be understood by a person of ordinary skill in the art in light of this disclosure, virtually any IHS environment that requires service or support may implement one or more aspects of the systems and methods described herein. Furthermore, certain aspects of the connected systems described herein may be implemented by computer manufacturers, software providers, and/or service or support companies.
• B. Service and Support Architecture
• Turning now toFIG. 1, a diagram illustrating an example of an environment where systems and methods for providing service and support to computing devices may be implemented is depicted according to some embodiments. As shown, each of any number ofclient devices102A-N may be an IHS or other computing device (generically referred to as “IHS102,” “client102,” “client device102,” or “device102”) including, for example, desktops, laptops, tablets, smartphones, and any other all-in-one (AIO) data processing device. In some situations,devices102 may be located in geographically distributed or remote locations, such as offices, homes, etc. Eachdevice102 may be operated by an individual end-consumer (e.g., lay person) or customer of a computer manufacturer or software provider, for instance. In some cases, two or more ofclient devices102A-N may be deployed within or managed by the same organization (e.g., a business).
• Tools intended to facilitate service and/or support ofclient devices102 includeservice technicians103,live support operators104, and/orbackend service105.Service technicians103 include trained employees or contractors that can travel to the site ofdevice102 or that can receive the physical device102 (e.g., at a retail store, by mail, etc.) or part(s) thereof in order to make repairs, for example. Live support operator(s)104 may be available, for instance, whendevice102 fails but it is sufficiently operational that it can still connect the user to operator(s)104 via chat, email, text messages, Voice-Over-Internet Protocol (VoIP) call, etc. Additionally or alternatively, the user ofclient device102 may place a conventional phone call to live support operator(s)104 (e.g., using a 1-800 number or the like). In some cases, live support operator(s)104 may interactively guide the user in an effort to correct problems with client device102 (e.g., troubleshooting).
• Backend service105 may include one or more servers and/or IHSs configured to perform one or more automated operations with respect todevice102. In various implementations,backend service105 may be configured to communicate with a service OS prior to and/or independently ofIHS102 being able to boot a main OS, and it may enable one or more support, diagnostics, or remediation operations to be performed remotely including, but not limited to, telemetry, error reporting, tracking, chat, etc.
• Entities102-105 may have access tonetwork101. In various embodiments,telecommunications network101 may include one or more wireless networks, circuit-switched networks, packet-switched networks, or any combination thereof to enable communications between two or more of IHSs. For example,network101 may include a Public Switched Telephone Network (PSTN), one or more cellular networks (e.g., third generation (3G), fourth generation (4G), or Long Term Evolution (LTE) wireless networks), satellite networks, computer or data networks (e.g., wireless networks, Wide Area Networks (WANs), metropolitan area networks (MANs), Local Area Networks (LANs), Virtual Private Networks (VPN), the Internet, etc.), or the like.
• For purposes of this disclosure, an IHS may include any instrumentality or aggregate of instrumentalities operable to compute, calculate, determine, classify, process, transmit, receive, retrieve, originate, switch, store, display, communicate, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an IHS may be a personal computer (e.g., desktop or laptop), tablet computer, mobile device (e.g., Personal Digital Assistant (PDA) or smart phone), server (e.g., blade server or rack server), a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. An IHS may include Random Access Memory (RAM), one or more processing resources such as a Central Processing Unit (CPU) or hardware or software control logic, Read-Only Memory (ROM), and/or other types of NVMs.
• Additional components of an IHS may include one or more disk drives, one or more network ports for communicating with external devices as well as various I/O devices, such as a keyboard, a mouse, touchscreen, and/or a video display. An IHS may also include one or more buses operable to transmit communications between the various hardware components.
• FIG. 2 is a block diagram of an example of an IHS. In some embodiments,IHS200 may be used to implement any of computer systems ordevices102A-N and/or105. As shown,IHS200 includes one ormore CPUs201. In various embodiments,IHS200 may be a single-processor system including oneCPU201, or a multi-processor system including two or more CPUs201 (e.g., two, four, eight, or any other suitable number). CPU(s)201 may include any processor capable of executing program instructions. For example, in various embodiments, CPU(s)201 may be general-purpose or embedded processors implementing any of a variety of Instruction Set Architectures (ISAs), such as the x86, POWERPC®, ARM®, SPARC®, or MIPS® ISAs, or any other suitable ISA. In multi-processor systems, each of CPU(s)201 may commonly, but not necessarily, implement the same ISA.
• CPU(s)201 are coupled to northbridge controller orchipset201 via front-side bus203.Northbridge controller202 may be configured to coordinate I/O traffic between CPU(s)201 and other components. For example, in this particular implementation,northbridge controller202 is coupled to graphics device(s)204 (e.g., one or more video cards or adaptors) via graphics bus205 (e.g., an Accelerated Graphics Port or AGP bus, a Peripheral Component Interconnect or PCI bus, or the like).Northbridge controller202 is also coupled tosystem memory206 viamemory bus207, and to hard disk drive (HDD)218.Memory206 may be configured to store program instructions and/or data accessible by CPU(s)201. In various embodiments,memory206 may be implemented using any suitable memory technology, such as static RAM (SRAM), synchronous dynamic RAM (SDRAM), nonvolatile/Flash-type memory, or any other type of memory. Conversely,HDD218 may include any magnetic, solid-state (SSD), or hybrid data storage device capable of storing an OS and other applications.
• Northbridge controller202 is coupled to southbridge controller orchipset208 viainternal bus209. Generally speaking,southbridge controller208 may be configured to handle various ofIHS200's I/O operations, and it may provide interfaces such as, for instance, Universal Serial Bus (USB), audio, serial, parallel, Ethernet, or the like via port(s), pin(s), and/or adapter(s)216 overbus217. For example,southbridge controller208 may be configured to allow data to be exchanged betweenIHS200 and other devices, such as other IHSs attached to a network (e.g., network101). In various embodiments,southbridge controller208 may support communication via wired or wireless general data networks, such as any suitable type of Ethernet network, for example; via telecommunications/telephony networks such as analog voice networks or digital fiber communications networks; via storage area networks such as Fiber Channel SANs; or via any other suitable type of network and/or protocol.
• Southbridge controller208 may also enable connection to one or more keyboards, keypads, touch screens, scanning devices, voice or optical recognition devices, or any other devices suitable for entering or retrieving data. Multiple I/O devices may be present inIHS200. In some embodiments, I/O devices may be separate fromIHS200 and may interact withIHS200 through a wired or wireless connection. As shown,southbridge controller208 is further coupled to one or more PCI devices210 (e.g., modems, network cards, sound cards, or video cards) and to one ormore SCSI controllers214 viaparallel bus211.
• Southbridge controller208 is also coupled to BIOS/UEFI212 and to Super I/O Controller213 via Low Pin Count (LPC)bus215. BIOS/UEFI212 includes non-volatile memory having program instructions stored thereon. Those instructions may be usable by CPU(s)201 to initialize and test other hardware components and/or to load an OS ontoIHS200. Super I/O Controller213 combines interfaces for a variety of lower bandwidth or low data rate devices. Those devices may include, for example, floppy disks, parallel ports, keyboard and mouse, temperature sensor and fan speed monitoring/control, among others. In various implementations,southbridge controller208 may be configured to allow data to be exchanged between BIOS/UEFI212 and another IHS attached to network101 (e.g., a remote server or other source of technical service) using wired or wireless capabilities ofnetwork adapter216.
• In some cases,IHS200 may be configured to provide access to different types of computer-accessible media separate frommemory206. Generally speaking, a computer-accessible medium may include any tangible, non-transitory storage media or memory media such as electronic, magnetic, or optical media—e.g., magnetic disk, a hard drive, a CD/DVD-ROM, a Flash memory, etc. coupled toIHS200 vianorthbridge controller202 and/orsouthbridge controller208.
• The terms “tangible” and “non-transitory,” as used herein, are intended to describe a computer-readable storage medium (or “memory”) excluding propagating electromagnetic signals; but are not intended to otherwise limit the type of physical computer-readable storage device that is encompassed by the phrase computer-readable medium or memory. For instance, the terms “non-transitory computer readable medium” or “tangible memory” are intended to encompass types of storage devices that do not necessarily store information permanently, including, for example, RAM. Program instructions and data stored on a tangible computer-accessible storage medium in non-transitory form may afterwards be transmitted by transmission media or signals such as electrical, electromagnetic, or digital signals, which may be conveyed via a communication medium such as a network and/or a wireless link.
• A person of ordinary skill in the art will appreciate thatIHS200 is merely illustrative and is not intended to limit the scope of the disclosure described herein. In particular, any computer system and/or device may include any combination of hardware or software capable of performing certain operations described herein. In addition, the operations performed by the illustrated components may, in some embodiments, be performed by fewer components or distributed across additional components. Similarly, in other embodiments, the operations of some of the illustrated components may not be performed and/or other additional operations may be available.
• For example, in some implementations,northbridge controller202 may be combined withsouthbridge controller208, and/or be at least partially incorporated into CPU(s)201. In other implementations, one or more of the devices or components shown inFIG. 2 may be absent, or one or more other components may be added. Accordingly, systems and methods described herein may be implemented or executed with other IHS configurations.
• As mentioned above, in various embodiments certain service capabilities may be built, at least in part, into aclient device102's BIOS/UEFI212. In that regard,FIG. 3 shows block diagram of an example of BIOS/UEFI212. Particularly, BIOS/UEFI212 includesNVM mailbox301 configured to store program instructions that, upon execution, provide and/or receive one or more service and support parameters orinformation302 to or fromcontrol logic303 of CPU(s)201 to implement one or more service and support applications described in detail below. In somecases NVM mailbox301 may serve as a “mailbox” to track issues and other information persistently. As noted above, however, at least a part of the aforementioned service capabilities may be provided via a service OS that is stored at least in part within a designated a partition of HDD318, and/or on a remote IHS accessible to BIOS/UEFI212 vianetwork101.
• C. Service and Support Applications
• In some embodiments, a variety of service and support applications may be at least partially embedded into BIOS/UEFI212 and/orNVM mailbox301, as described below.
• i. Automated Hardware Client Device Service and Support
• Systems and methods described herein may include a service and support application configured to provide automated services. In some embodiments, client device BIOS level intelligence may be provided to execute self-diagnosis and to assist in automated services. Service capabilities are built into client device BIOS diagnostics pre-boot, service OS on disk, or boot from cloud. Moreover, these capabilities may be integrated with a services backend for automated client device error reporting, tracking, chat, remediation, etc.
• In some embodiments, an automated diagnostics procedure of an automated service and support application may include performing a BIOS diagnostics to discriminate hardware from software issues (e.g., broken HDD or corrupt OS). Then, BIOS/UEFI212'sNVM mailbox301 may be used to track issues persistently from BIOS, pre-OS, OS, and/or backend sources.
• Upon detection of a failure, a determination may be made as to the severity of that failure (e.g., whether the failure is severe, such as in a no-video situation, a no-network scenario, etc., or whether it is a simple failure, such as an OS problem), and remedial action(s) may then be taken by the automated service and support application as deemed appropriate. For example, if a network is not available, a Quick Response (QR) code or audio may be used to provide diagnostic failure and device identification information. Conversely, if the network is available, the automated service and support application may activate a “phone home” capability upon detection of a failure, and it may boot the client device to a service OS.
• In that scenario, the client device may connect directly with a backend service Application Programming Interface (API) to initiate a warranty check (e.g., via hardware service tag as hardware ID), generate a service case, update debug data, initiate recovery or remediation operations, etc. In some cases, the automated service and support application may trigger an automatic dispatch of customer replaceable units (CRUs), parts, or components within the client device.
• At the “point of need,” which often coincides with the “point of failure,” the automated service and support application may make service offers based on failure diagnoses. For example, such service offers may include an out of warranty upsell, warranty upgrade, additional service offers (e.g., HDD recovery for dead drive upsell), warranty carry in capability (e.g., report closest repair facilities for carry in service), etc.
• Moreover, with respect to recovery and remediation, the automated service and support application may provide remote control, remote scripting/diagnostics, live customer support, backup, re-imaging and OS re-install via local factory image or via web, and the like.
• ii. No-Video Support
• Systems and methods described herein may include a service and support application configured to provide technical support in no-video situations, which are otherwise difficult to troubleshoot. In many cases, whenclient device102 is not capable of outputting a video signal, users have no other option but to place a phone call to the manufacturer, because the device itself can provide no help.
• To address this, and other concerns, a service and support application as described herein may include a audio-only support system, for example, similar to an automated phone support system or Interactive Voice Response (IVR), but that is local toclient device102 and capable of running in a pre-OS or pre-Boot environment. While a customer is interacting with the service and support application,client device102 can run a diagnostics procedure. When appropriate, the service and support application may handoff the local automated audio support to online voice support from the IHS manufacturer. Ifnetwork101 is unavailable,client device102 may prompt the user to connect directly to a nearby device distinct fromclient device102 to perform one or more of these operations.
• In some embodiments, the service and support application may include pre-OS availability of audio-based troubleshooting, offline audio support concurrent with diagnostics, and/or merging or handover between offline and online audio support. The service and support application may also prompt the user to make peer-to-peer (P2P) connection to a nearby device, readout codes for diagnosis/dispatch verification, and/or prompt the user to add or insert external storage to which to output diagnostic results.
• iii. Mayday Beacon
• Systems and methods described herein may include a service and support application configured to provide an automated and authenticated mayday beacon, with a cost-effective 1-to-1 support for verifiedclient device102's failures.
• Whenclient device102 experiences a fault or hang before its main OS is made available, a wireless signal beacon (e.g., Bluetooth, Wi-Fi, etc.) may be sent (e.g., on a periodic basis) containing verification of the device credentials issued at the time of manufacture, details regarding the fault and a direct link to the manufacturer's support, decision tree location, and/or whether a premium account is linked. The beacon may be authenticated directly to a support representative with all failure information logged and available. This technique may prevent erroneous support calls by verifying the user has actually experienced a failure and authenticating that the proper support level has been funded, which promotes a low cost, one-on-one support service.
• In some embodiments, the service and support application may be configured to broadcast a distress signal with credentials to make authenticated jump to a support site provided bybackend services105 from a secondary device or infrastructure. A certificate may be issued from the manufacturer containingclient device102's platform, user information, and/or service level. Such a certificate and a landing page for service may be passed automatically whileclient device102 is out of service. Also, the service may be rendered utilizing secondary device or infrastructure via authenticated and verifiedclient device102 experiencing failure.
• iv. Network-Based Recovery and Service
• Systems and methods described herein may include a service and support application configured to provide network (e.g., Internet) recovery and service.
• Whenclient device102 fails, it may “phone home” and boot, frombackend services105, a service OS to provide automated service and support. A service and support application in BIOS/UEFI212 may include, for example, a boot loader, where to go (e.g., an IP address), booting proper image for machine, and/or a service application. As such, the service and support application may provide a smarter BIOS/UEFI212, smart diagnostics in BIOS/UEFI212, intelligent boot selection to local drive or web, and IP-awareness, among other features.
• In some implementations, the service OS may be supported on many platforms and on many versions of those platforms. For example, a single platform (e.g., having a model name or number) may be shipped from the manufacturer with different hardware configurations (e.g., different CPUs, etc.), thus each combination of platform and version requiring that different, specific drivers be built into or provided for in the service OS.
• In some embodiments, the service and support application may be configured to provide a Unified Extensible Firmware Interface (UEFI) BIOS module with smart diagnostics and IP support intelligently controls boot to a service OS.Client device102 connects to backendservices105 to get proper and latest service OS for that particular device. Backend service orserver105 may receive a client manifest, and it may dynamically serve a service OS kernel, drivers, and a service application toclient device102 for recovery and/or remediation.
• v. Reducing Perception of Wait Times
• Systems and methods described herein may include a service and support application configured to improve customer experience while downloading a recovery OS by reducing the perception of wait time.
• Whenclient device102 has a malfunction, it can boot to an alternate OS. In some cases, the alternate OS is downloaded vianetwork101 beforeclient device102 is able to boot. The download time is variable, often nontrivial, and may negatively affect customer perception. To counter this, the service and support application may estimate the download time of the alternate OS and, based on an assessment of the delay, may “pull forward” one or more low-bandwidth activities and/or options that the customer may need or desire to do anyway (e.g., updating contact information), thus helping save customer time and reducing the perception of delay.
• In some embodiments, the service and support application may be configured to prioritize lower-bandwidth tasks based on estimated OS load time. Prioritization of activities may be based, for example, upon data about malfunction. As such, the application may enable user input or interaction while OS is downloading (e.g., updating contact information, describing the problem that happened before failure, etc.). The application may also submit a phone number for text alerts when failedclient device102 is ready, and it may start a local interactive debug troubleshooting operation while the OS is being downloaded.
• vi. Identity Continuity in Service of Failed System
• Systems and methods described herein may include a service and support application configured to provide identity continuity in the servicing of a failedclient device102.
• Whenclient device102 fails and needs service, a user may need to enter service credentials on a service web portal provided by backend service orserver105, whether accessing the portal directly or via a service OS. However, the user may not recall such infrequently-used credentials at the point of need. By storing both a main OS's user credential hash and a service portal token, a service and support application can authenticate the user, and then automatically submit the service portal token to log user into the service portal without manual entry of customer credentials. This method may also be used to allow access to customers Wi-Fi profiles, and other type of data that needs protection.
• In some embodiments, the service and support application may be configured to use a BIOS's “mailbox” to communicate one or more services token(s) to enable a single-sign-on procedure, while protecting the token(s) with user credentials.
• vii. Smart Diagnosis and Triage of Failures
• Systems and methods described herein may include a service and support application configured to perform smart diagnosis and triage of client device failures.
• In some cases, the application may provide an automated method of hardware exoneration, identifying software versus hardware issues with targeted debug. POST may be used to detect issues during power on sequence, then those results may be used for firmware-based diagnostics for next level of hardware diagnostics. Main OS, POST and firmware based diagnostic results may be stored on the client device's BIOS's NVM or “mailbox” as device health data. Incase client device102 is not able to boot its main OS, a service OS may be started and uses health data to either run even more extensive hardware diagnostics or to run software fault detection and remediation test. Cloud connection toclient device102's manufacturer orbackend service105 may facilitate the download of updated tests, reporting of issues, and initiation of replacement parts dispatch.
• In some embodiments, the service and support application may be configured to use a BIOS's NVM or “mailbox” to aggregate device health data. The application may use firmware and/or a service OS. Each stage of diagnostics may use information from previous diagnostics results to target more detailed but specific subsequent tests.
• viii. Smart Diagnosis Using Hosted Resources
• Systems and methods described herein may include a service and support application configured to perform smart diagnosis using hosted resources. Whenclient device102 cannot boot after repeated attempts, it may begin a process to perform self-evaluation and potentially self-repair operations. Because having all executable diagnostics and repair modules present in the non-bootable system would be costly, operations may involve successively loading software modules from aremote support source105. But, modules loaded through internet/wireless networks101 are likely slow to download, and therefore should be reduced or minimized to be tailored exactly as needed for a given process.
• To address these, and other problems, in some embodiments a service and support application may be configured to upload test results tobackend service105, which automatically determines a subsequent module to be downloaded based on client device data and/or historic analysis of other client devices. The application may provide a remote boot of diagnostic and repair software modules. Appropriate modules may be selected and/or minimized to the next diagnosis stage in order to facilitate transfer over slow communications channels. A service may provide a reverse proxy for a hosted module to be loaded so thatclient device102 may boot from a single Uniform Resource Locator (URL) for each process.
• ix. Adaptive Boot Order
• Systems and methods described herein may include a service and support application configured to intelligently alter a boot order to aid in automated client device diagnosis and repair. Whenclient device102 fails to completely boot, it does not move on to another component, as set in the boot order, if a previously attempted component remains available for boot. Often the process gets stuck trying to boot and repair the main OS indefinitely. The pre-set boot order remains static and unaltered.
• In some embodiments, by building intelligence into BIOS/UEFI212 for determining a boot order forclient device102, a service and support application may be configured to break out of a failing sequence and load alternative OSs and/or repair and diagnostic modules from various local or remotely available resources selected by their availability, performance, or content. Depending upon the success of each stage,client device102 may change the boot order again to try another source. A successful repair may lead back to booting the main OS as the primary boot resource. An alternative or service OS may result as the final stage if the main OS cannot be made bootable.
• In some embodiments, the service and support application may be configured to dynamically change a boot order based upon conditions ofclient device102. The application may also setclient device102 in temporary or “permanent” boot orders based upon the completion stage of the diagnosis and repair.
• x. Exporting of Failure and Diagnostic Data
• Systems and methods described herein may include a service and support application configured to export failure and diagnostic data from a malfunctioning client device.Client device102 may sometimes malfunction such that it cannot provide output or accept input from a user. It may still function at a low level, however, in order to capture its own failure codes and run diagnostics. These codes and diagnostic results are written to internal storage and are useful for system remediation, but unfortunately remain captive on the malfunctioning client device.
• To address these, and other problems, a service and support application may create an embedded capability that is triggered by a malfunction, identifies the failure/diagnostics data, and exports the data upon insertion of an external storage device. The external device may then be taken to a functioning IHS or other client device, which can receive the data for local analysis and/or upload it for analysis or record keeping.
• In some embodiments, the service and support application may be configured to export the data to an external device having a marker file. The marker file may be generated by an IHS manufacturer or software provider, and identifies the external device as belonging to an authorized service technician or other party. As such, a service mode may be provided for malfunction situations in which a user cannot interact with or extract data from failedclient device102. Normal behavior that occurs when inserting an external storage device may be overridden in the service mode, and insteadclient device102 may export related failure/debug data to the external device. The service mode may be independent of the main OS.
• xi. Technician Access to Service Data
• Systems and methods described herein may include a service and support application configured to provide technician access to only services data on an encrypted drive. For diagnosis and remediation,client device102 may use services data (e.g., system telemetry, failure and diagnostics data, services history, etc.). If a system has OS volume encryption (e.g., BitLocker) and fails over to a service OS, the service OS cannot typically access the services data due to encryption. That is, the latest and most valuable services data is trapped.
• To address these, and other concerns, service and support application may create a separate services data partition in local storage (e.g.,client device102's own hard drive), also encrypted for consistency with user intent. The key for the services data partition may be different than the key used for the remainder of the volume encryption, and may be stored bybackend service105 with user permission to allowservice technician103 access in controlled support situations. As such, services data may be kept outside the inaccessible encrypted OS partition while still protected.
• In some embodiments, the service and support application may be configured to create a services data partition that is encrypted differently (e.g., different key and/or encryption algorithm) thanclient device102's main OS volume for purposes of services access. Access to the separately encrypted data may be useful to services applications and only visible to an authorized technician. Also, the application may provide the ability to pull encryption key from cloud and decrypt service data on device distinct from the client device, for example, using technician credentials (e.g., whennetwork101 is not accessible by client device102).
• xii. Protecting the Service OS Administrator's Password
• Systems and methods described herein may include a service and support application configured to protect the service OS administrator's password while allowing technician one-time execution with elevated privileges. An initial password for a service OS may be created using a One-Time Password (OTP) technique and a seed stored onclient device102's BIOS/UEFI212'sNVM mailbox301. The seed and a hardware service tag may be sent tobackend services105 to provide a mechanism forservice technician103 or live support operator(s)104 to run privileged applications in the service OS without using a master password. In some embodiments, application of OTP in a support scenario may enable higher security for remote management and debug operations.NVM mailbox301 may be used for storing initial seed at factory tied to the client hardware service tag. A service technician at failure time may generate a code to request administrator permissions.
• xiii. Automatic Stop and Boot to Service OS
• Systems and methods described herein may include a service and support application configured to provide automatic system stop and boot to a service OS for forensics analysis. In some embodiments, detection of suspicious activity for secure systems may result in automated boot to service OS with automated forensics lockdown and analysis outside the potentially compromised main OS. The application may combine security intrusion or behavior capabilities with a service OS to provide new forensics features. For example, detection of intrusion or malware inclient device102 may initiate lock down mode boot to the service OS. The service OS then connects or phones home to backendservices105 report a potential security incident, and initiates data forensics collection.Client device102 may maintain a lockdown mode at BIOS level controlled by policy to maintain security ofnetwork101 and data for forensic analysis.
• xiv. Migrating Contents of an Internal Storage Partition
• Systems and methods described herein may include a service and support application configured to migrate contents of an internal storage partition to a replacement storage device.
• In some embodiments, data contained on a secondary partition ofclient device102's internal drive storage may be migrated from an old or existing drive to a replacement or upgraded drive by storing it in Dynamic RAM (DRAM) while the drive is hot-swapped. If DRAM capacity is insufficient, overflow may be handled by external storage (e.g., USB drive), for example. In another embodiment, a Solid State Drive (SSD) portion may instead be a secondary partition on a standard hard drive. As such, an application may migrate a specified drive partition into DRAM, use external storage for data that exceeds the capacity of DRAM, and/or recognize and provisions replacement storage with contents of drive partition.
• xv. Using a Service OS Via a Hypervisor
• Systems and methods described herein may include a service and support application configured to increase the effectiveness of a service OS by utilizing a custom hypervisor.
• A conventional service OS may be configured to run onclient device102 only when the main OS is suspended. Such a conventional service OS may not be able to effectively monitor real-time events in the main OS as they occur. For example, a conventional service OS may only be able to examine the state of the primary disk, data, etc. using residual data collected by the main OS when the main OS was running. To address these, and other concerns, a service OS as described herein may run in a hypervisor (in a first tier next to the main OS, or in a second tier), and the hypervisor may allow the service OS full access to the resources of the primary OS. Accordingly, dynamic state of the primary OS may be monitored either constantly or periodically and actions and reports may occur immediately (a “watchdog” OS).
• In some embodiments, a hypervisor environment may provide a service OS ofclient device102 with full access to the resources of the main OS (but not necessarily vice-versa, for example, to keep the main OS from being corrupted). The service OS may run as a peer of the primary OS. The peer, service OS may be configured to monitor for process, memory, disk and other resources of the main OS, and may be allowed to alter them as required.
• D. Methods for Providing Client Device Service and/or Support
• FIG. 4 is a flowchart of a method for providing service and support in a computing device. In some embodiments,method400 may be performed, at least in part, by BIOS/UEFI212 and/or CPU(s)201 ofclient device102, for example, whenclient device102 is operating in degraded state (e.g., no video, hard drive fault, etc.).
• Atblock401,method400 includes attempting to bootclient device102. For example, block401 may be executed in response to a power-on or reset event.Block402 determines whether a Power-On-Self-Test (POST) procedure has been successfully performed uponclient device102 by BIOS/UEFI212. If so, then block404 determines whether a main OS has been successfully booted. In some cases, a successful boot of the main OS may include a complete success; in other cases, however, a “successful” boot may include cases where the main OS is booted in safe mode, or the like, with less than all of its functionality available to a user. Ifblock404 detects successful boot of the main OS, then control ofclient device102 is passed to the main OS atblock406, and the method ends. In that case, support and/or service issues may be handled by the main OS.
• Conversely, if the POST operation fails atblock402, service and support may be provided in a pre-boot environment atblock403. Examples of service and support procedures available toclient device102 in such a scenario include, but is not limited to, detecting network availability, use of QR codes or the like (with or without network connections), collection and transmission of telemetry data and/or event logs, alerts and indications of failures, and procedures for dealing with no-video scenarios, as outlined above.
• If the main OS fails to boot atblock404, block405 then determines whether a service OS can be booted. In some cases, the service OS may be initiated from a memory local to the client device. For example, the service OS may be stored inmailbox301 or in a designated partition ofHDD218. Alternatively, the service OS may be loaded from abackend service105 over network101 (e.g., cloud boot). If the service OS is not capable of being booted atblock405, then service and support may again be provisioned within the pre-boot environment atblock403. Otherwise, service and support operations may be provided in a pre-OS environment atblock407, beforemethod400 ends.
• In various implementations, BIOS/UEFI212 may be configured to use a “boot strike count” as part of a failure detection procedure. That is, the number of unsuccessful main OS and/or service OS boot attempts may be kept by BIOS/UEFI212, and that information may be used by one or more of the aforementioned service and support operations in subsequent boot attempts.
• As noted above, in some cases, service and support may be provided to a computer device such asclient device102 bybackend services105 vianetwork101. In that regard,FIG. 5 is a flowchart of a method for providing backend services and support to a computing device. In some embodiments,method500 may be performed, at least in part, by BIOS/UEFI212 and/or CPU(s)201 ofclient device102 in cooperation withbackend services105, for example, whenclient device102 is operating in degraded state (e.g., no video, hard drive fault, etc.), either inpre-boot environment402 orpre-OS environment407 ofFIG. 4.
• Atblock501,method500 includes determining whether access tonetwork101 is available toclient device102. If not, then service and support operations may be provided as local remediation operations (e.g., QR code services, etc.) atblock502. If there is network access, however, block503 includesclient device102 “phoning home” to reachbackend services105, which in turn may perform one or more checks. Examples of such checks include, but are not limited to, warranty and service entitlement checks performed using theclient device102's service tag or other identifying information.
• Atblock504,method500 includes uploading client device telemetry and/or debug data tobackend services105. For example, the telemetry and/or debug data may be used bybackend service105 to iteratively improve diagnostics and fault isolation. Then, atblock505,method500 includes any number of remote remediation and service operations performed bybackend services105. Examples of such operations include, but are not limited to, auto dispatch for CRUs, point of need services (such as warranty upsells, warranty upgrades, service offers, etc.), and HDD recovery (with optional reporting of closest location, office, or store available for carry-in service by the user). Other operations may include remote control of one or more components ofclient device102, chat support, backup, re-imaging, OS re-install via local factory image or cloud, etc.
• It should be understood that various operations described herein may be implemented in software executed by logic or processing circuitry, hardware, or a combination thereof. The order in which each operation of a given method is performed may be changed, and various operations may be added, reordered, combined, omitted, modified, etc. It is intended that the invention(s) described herein embrace all such modifications and changes and, accordingly, the above description should be regarded in an illustrative rather than a restrictive sense.
• Although the invention(s) is/are described herein with reference to specific embodiments, various modifications and changes can be made without departing from the scope of the present invention(s), as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of the present invention(s). Any benefits, advantages, or solutions to problems that are described herein with regard to specific embodiments are not intended to be construed as a critical, required, or essential feature or element of any or all the claims.
• Unless stated otherwise, terms such as “first” and “second” are used to arbitrarily distinguish between the elements such terms describe. Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements. The terms “coupled” or “operably coupled” are defined as connected, although not necessarily directly, and not necessarily mechanically.
